Looking for help on getting a Kinze 3600 ISOBUS retrofit install working.

We have a Kinze 3600 12 row (finger and mechanical) with a KPM2 monitor. We have installed the  ISOBUS kit (PMM , PCM and associated wiring) and electric clutches .

We want to just control the shutoffs.  The KPM2 can continue to monitor the seed.

The tractor has the JD Gen4 4640 to run the ISOBUS.

While trying the planter on stubble ground, the implement switches work, the shaft sensors work and the section control page shows sections being on while trying to plant.

The Kinze VT screen shows 12 rows error/alarm (no seed) and the work light (paint) doesn't show on the 4640 guidance screen.

How do I tell / configure it to ignore the seed tubes that aren't there?

Thx

Bill
